Additional Results / Output parameters
Additional results are written in the plugin folder Kalypso-NA to model hydrological processes in SUDS and to model flood routing with and without backwater effects.
Output parameters of SUDS
For each layer of a spatial data structure on the local scale (namely SUDS or LSDMs) the soil moisture balance equations are solved. The following output parameters are written as time series per time step (t), with the time step size ( Δt) and per unit area (m2) of the SUDS structures in *.dat-format (date, time and value). For evaluation purposes the results with and without backwater effect computation are given.
- Influx (mm/ Δt) per LSDM structure.
- Rainwater harvesting outflux (mm/ Δt) per LSDM structure. The potential and the actual rainwater harvesting time series are given.
- Pre-emptying outflux (mm/ Δt) per LSDM structure.
- Water (drainage) outflux per layer and sum of drainage outflux per LSDM structure(mm/ Δt).
- Exceedance outflux (mm/ Δt) per LSDM structure.
- Evapotranspiration (mm/ Δt) per LSDM structure.
- Interception storage volume (mm/ Δt) per LSDM structure.
- Water volume per layer and sum of water volume in the LSDM structure without and with backwater effect computation (mm/ Δt).
The following output parameters are written as aggregated sum of out- and influxes as well as changes in the storage volumes per simulation run and per spatial data structure (namely overlays or subcatchment):
- Sum of influx in form of precipitation (mm).
- Sum of influx from linked overlays (SUDS, LSDMs)(mm).
- Sum of interception storage volume (mm).
- Sum of potential and actual evaporated water (mm).
- Sum of infiltrated water into the permeable material of the top layer (mm).
- Sum of transpired water over all layers in the root zone (mm).
- Sum of exceedance flow of the topmost layer and surface runoff (mm).
- Sum of lateral drainage fluxes of each layer (mm).
- Sum of actual rainwater harvesting (mm).
- Sum of actual controlled pre-emptying drainage fluxes (mm).
- Sum of percolation into the groundwater reservoir (mm).
- Sum of depression losses from impervious surfaces (mm).
- Change in water storage during the simulation run (mm) = ΔV.
- Area (m2) per spatial data structure.
For each spatial data structure the water balance computation in the form of mass-balance is calculated for evaluation purpose in the following form:
if Vin − Vout − ΔV , 0 → A warning and the error value is given. where Vin is the influx (mm), Vout is the outflux (mm) and ΔV is the change in water storage (mm).
Output parameters of the flood routing computation with and without backwater effects
The output parameters of flood routing computations are the formal parameters and the WVQ-relations before and after the calculation of backwater effects with the KM1- and KM5-method. A comparison of the inflow and outflow hydrograph volumes
per stream segment is provided for evaluation purpose. Additionally, the time series with a temporal resolution of Δt for the following output parameters per stream segment and control structure are given:
- Storage volume before and after backwater effect computation (m3).
- Water level before and after backwater effect computation (m a.s.l.).
- Control system settings per time step (-).
- Discharge per junction node (m3/s).
- Evaporation rates from open water surfaces (mm/ Δ t).
- Exceedance flow of reservoir stream segments (m3/s).
For evaluation purposes in the form of mass-conservation and for checking the calculated flood routing parameters, the following output is given per linear data structure:
- Total inflow hydrograph volume (m3).
- Total outflow hydrograph volume (m3).
- Change in water storage per simulation run (m3).
- Computed (formal) parameters of the KM1-method:
- Retention coefficient Kkm (s).
– Characteristic length Lc (m). – Number of characteristic lengths n (-). • Computed (formal) parameters of the hydraulic capacity per stream segment (in the form of WVQ-relations): – Water level (m). – Volume (m3). – Discharge (m3/s). – Wetted cross section (m2). – Hydraulic radius (m). – Flow velocity (m/s).
